14 Questions
The Bony pelvis is made up of what bony parts?
Sacrum & 2 Os Coxae bones
The sacral promontory is_________________?
A prominent ridge on the anterior surface of the first sacral segment that separates the abdominal and pelvic cavity.
Which three bones make up the Os Coxae (Innominate bones)?
Ilium, Ischium, and Pubis.
Which statements are correct regarding the Ilium?
The ilium is the largest and most superior Os coxae. It contains the iliac crest, iliac fossa, the arcuate line, and creates the upper portion of the acetabulum with its body.
The arcuate line is also known as the__________?
Linea Terminalis
Which landmarks can be used to separate true and false pelvis?
Arcuate line, pelvic brim, and linea terminalis.
What statements are true about the pubis?
The pubis is part of the os coxae, its also called the pubic bone, forms the lower anterior portion of the acetabulum, and meets at anterior midline to form the pubic symphysis.
Which bone of the innominate bones is compromised of a body and two rami, is the inferior portion of the os coxae and its body forms the lower posterior portion of the acetabulum?
Ischium
The pelvis is divided into ___________ (greater) pelvis and ________ (lesser) pelvis by an oblique plane extending from the upper anterior margin of sacrum to the upper margin of the pubic symphysis.
The pelvic brim is the boundary line that delineates the boundary of the ventral and dorsal cavities.
False
Below the pelvic brim is the ______ _____________ and above the pelvic brim is the ______ _____________.
The pelvic brim is the boundary line that delineates the boundaries of the ____________ and ________________ cavities.
Which of the following is a true statement?
The true pelvis is divided by the pelvic diaphragm into the main pelvic cavity and perineum.
The perineum covers and partially fills the inferior aperture of the bony pelvis.
True
Study Notes
Bony Pelvis
- The bony pelvis is made up of sacrum, coccyx, and two os coxae (innominate bones)
- The sacral promontory is the superior aspect of the sacrum
- The three bones that make up the os coxae (innominate bones) are ilium, ischium, and pubis
- The ilium is the largest and widest bone of the os coxae, forming the ala, gluteal surface, and iliac crest
- The arcuate line is also known as the linea terminalis
- The pelvic brim (linea terminalis) separates the true pelvis from the false pelvis
- The pubis is the anterior inferior portion of the os coxae, consisting of a body and two rami
- The ischium is the bone of the innominate bone that is compromised of a body and two rami, forming the inferior portion of the os coxae and the lower posterior portion of the acetabulum
- The pelvis is divided into greater pelvis and lesser pelvis by an oblique plane extending from the upper anterior margin of sacrum to the upper margin of the pubic symphysis
- The pelvic brim is the boundary line that delineates the boundary of the abdominal cavity and the pelvic cavity
- Below the pelvic brim is the lesser pelvis and above the pelvic brim is the greater pelvis
- The perineum covers and partially fills the inferior aperture of the bony pelvis
